If you can't see the dye anywhere along the a/c system, it could be inside the box under the dash. The evaporator coil in there could be the source of the leak.
I did the retrofit on mine a few years ago with no problems. I flushed the lines, compressor and condensor, changed the dryer, and put PAG oil in for lubrication. Then I pulled a vacuum on the system for about an hour, then closed it off to see if it would hold. Once I was sure it didn't leak, I started charging the system. Since then, it's been flawless, and it gets chilly in the car pretty quick.
